Not applicable to this application.
1. Field of the Invention
The present invention relates generally to fertilizer applicators and more specifically it relates to a liquid fertilizer application system for efficiently dispensing and placing liquid fertilizer within a furrow to minimize germination injury.
2. Description of the Related Art
Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.
Fertilizer applicators have been in use for years. Typically, the placement of fertilizer in close proximity to seeds during the planting process is done to improve crop yields. Current applicators place fertilizer to the side of the seeds in the furrows, on top of the seeds in the furrows, in bands on the soil near the seed rows or broadcast on the soil above the seed rows. Unfortunately, current fertilizer applicators utilized in the farming industry directly apply fertilizer to the seed which results in burning of the seed thereby increasing germination injury.
While these devices may be suitable for the particular purpose to which they address, they are not as suitable for efficiently dispensing and placing liquid fertilizer within a furrow to minimize germination injury. Conventional fertilizer applicators tend to directly apply the fertilizer upon the seed thereby increasing germination injury.
In these respects, the liquid fertilizer application system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of efficiently dispensing and placing liquid fertilizer within a furrow to minimize germination injury.
In view of the foregoing disadvantages inherent in the known types of fertilizer applicators now present in the prior art, the present invention provides a new liquid fertilizer application system construction wherein the same can be utilized for efficiently dispensing and placing liquid fertilizer within a furrow to minimize germination injury.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new liquid fertilizer application system that has many of the advantages of the fertilizer applicators mentioned heretofore and many novel features that result in a new liquid fertilizer application system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art fertilizer applicators, either alone or in any combination thereof.
To attain this, the present invention generally comprises a fertilizer tube having an input opening and a discharge opening, a mounting tab and a centering bracket. The fertilizer tube is attached to a shank of a planter implement using the mounting tab and is additionally positioned by the centering bracket. The discharge opening of the fertilizer tube is located in front of a scraper attached to the planter implement seed tube. The discharge opening of the fertilizer tube is forward of the seed tube to allows for the application of the fertilizer into a prepared furrow prior to placement of the seed.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and that will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of the description and should not be regarded as limiting.
A primary object of the present invention is to provide a liquid fertilizer application system that will overcome the shortcomings of the prior art devices.
A second object is to provide a liquid fertilizer application system for efficiently dispensing and placing liquid fertilizer within a furrow to minimize germination injury.
Another object is to provide a liquid fertilizer application system that increases crop yield.
An additional object is to provide a liquid fertilizer application system that reduces fertilizer usage.
Other objects and advantages of the present invention will become obvious to the reader and it is intended that these objects and advantages are within the scope of the present invention.
To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated and described within the scope of the appended claims.
Various other objects, features and attendant advantages of the present invention will become fully appreciated as the same becomes better understood when considered in conjunction with the accompanying drawings, in which like reference characters designate the same or similar parts throughout the several views, and wherein:
A. Overview
Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views,
B. Fertilizer Tube
The fertilizer tube 20 is preferably made of a rigid material that will not significantly distort when welded to or when assembled onto the shank 15 of a planter implement. The fertilizer tube 20 is preferably made of a material which will withstand contact with chemicals normally used in farming operations and long periods of exposure to moisture such that it will not rust. The fertilizer tube 20 is preferably constructed of circular shaped tubular material, but is not limited to being only circular.
As best shown in
As shown in
As best shown in
The segments 22, 24, 26, 28 of the fertilizer tube 20 are preferably bent at preset angles in order to route around the shank 15 structure of the implement. The first segment 22 is bent up in relation to the second segment 24 preferably forming an angle of approximately 120 degrees. The second segment 24, as best shown in
C. Mounting Tab
The plate 32 of mounting tab 30 is preferably made of a rigid metal material that will not significantly distort when welded to or when assembled onto the shank 15 of a planter implement. The plate 32 of mounting tab 30 is preferably made of a material which will withstand contact with chemicals normally used in farming operations.
As shown in
As shown in
D. Centering Bracket
The centering bracket 40 is preferably made of a rigid metal material that will not significantly distort when welded to. The centering bracket 40 is preferably made of a material which will withstand contact with chemicals normally used in farming operations. The centering bracket 40 is formed into a V-shaped structure with a rounded bottom portion so the inside diameter of the rounded bottom matches the outside diameter of the fertilizer tube 20.
The centering bracket 40 is preferably welded to the fertilizer tube 20, however it can be appreciated that other methods of attachment could be used. As shown in
E. Operation of the Invention
In use, a liquid fertilizer application system 10 is attached to each shank 15 of a planter implement. A liquid fertilizer application system 10 is procured by attaching both a mounting tab 30 and a centering bracket 40 to a fertilizer tube 20. The fertilizer tube 20 is attached in front of the shank 15 of the planter implement with the discharge opening located slightly below the shank 15.
To assemble each liquid fertilizer application system 10 to the planter implement, the mounting tab 30 attached to the fertilizer tube 20 is attached to each shank 15 by means of hardware (e.g. socket head cap screw) extending through a aperture located in the shank 15, securing at the fastener 34 attached to the mounting tab 30. The hardware is initially loosely attached to assure the centering bracket 40 is placed correctly around the shank 15. After the centering bracket 40 and fertilizer tube 20 are positioned correctly, the hardware is tightened to the mounting tab 30.
As best shown in
Following the installation of each liquid fertilizer application system 10 to each shank 15 on the planter implement, a hose 19 is attached to each fertilizer tube 20 input opening 23 as shown in
